    Helping the overheating problem
    By  GILBERT,  a  Verified Buyer  on  August 31, 2021
    Had a overheating problem with my 2001 Dodge and I used the ams oil 5w30 synthetic oil and a water pump from a 6.7 and haven't had an overheating problem towing, I know this wasn't a complete fix by using the oil but when I used the thicker conventional oil I always had this problem so I highly recommend this product.
    Bottom Line
    Yes, I would recommend this to a friend.
